So this just started recently. My 08 express van 50k miles 6.0 engine. Not exactly sure which trans it has. Just started hard shifting when cold. Like first thing in the morning. I warm up my truck then I leave the driveway. 1st shift is hard and sometimes 2nd shift is hard. Then it smooths out and no problems for the remainder of the day. Unless it sits long enough (8 hours or so for example) then it will do the hard shift again
any recommendations on where to look or start would be great. Thanks in advance
